Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-100
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-100
The AirTAC SAIJ80X600-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 100 mm. This creates a usable 500-600 mm stroke window, providing exact end-position tuning at commissioning without swapping out the unit or adding external stops. It delivers a robust 2513 N pull force at 0.5 MPa.
This model uses a 25 mm SUS420J2 stainless steel piston rod (code A) with an M20x1.5 thread, which handles side loads well, though the long 600 mm stroke still requires an external guide to prevent rod bending. It omits the FB, CA, CB, and CR mountings, offering the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-100 Is Used
Machine Changeovers
Dial in the 500-600 mm travel window during product-size changeovers without physically swapping cylinders or remachining external hard stops.
End-Position Tuning
Fine-tune the retract end-position at commissioning to perfect the seating of parts, absorbing minor mechanical setup variances on the fly.
Variable Stroke Stops
Set a precise, variable end-stop for long-travel automated equipment, adjusting the 600 mm nominal stroke exactly to the process requirements.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-100 the Right Cylinder?
Choose this 80 mm bore when you need higher force than the 63 mm version (1559 N pull at 0.5 MPa) but less bulk than the 100 mm bore (3681 N pull). The adjustable stroke is ideal for product-size changeovers on a line, letting you dial in the 500-600 mm travel window on the fly instead of machining new hard stops. It features PT tapered ports (G3/8) and no sensor magnet. Because the stroke is 600 mm, an external guide rail is highly recommended to manage side loading. For load-holding without live pressure, select the SAIL or BSAI series, as the SAIJ adjuster is only a stop, not a lock.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-100 FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa operating pressure, it delivers up to 513 kgf.
The rear adjuster screw lets you shorten the 600 mm nominal stroke by up to 100 mm, creating a usable 500-600 mm travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without live air.
